Transcript for TSA Workers Allegedly Stealing From Passengers and Sleeping on Duty

Their job is to keep america's airports safe and most tsa agents do it wrl. Managing those endless security lines, keeping passengers moving and protected. But a new government report out today detailed some disturbing trends at the tsa, agents asleep on the job, caught stealing from passengers, fast tracking frenlds and family. Experts say it could also be dangerous. Lisa stark starts us off. Reporter: Tsa agents sleeping at the airport. Abandoning their posts. Even stealing from passengers.

The agent tonight tells us it has zero tolerance for misconduct and holds its employees to the highest ethical standards.
